CHARLES H. STRATTON, OF SALEM, OHIO.

WAGON .JUMP-SEAT.

'SPECIFICATION forming part of Letters Patent No. 299,437, dated May 2,7, 1884.

Application tiled November 8, 1883. v(No model.)

To all whom t may concern.-

Be it known that I, CHARLES H. STRAT- ToN,a citizen of the UnitedStates of America, residing at Salem, in the county of Columbiana and State of Ohio, have invented certain new and useful Improvements in Jump-Seats; and I do hereby declare the following to be a full, clear, and exact description of the'invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters or figures of reference marked thereon, which form a part of this specication.

My invention relates to jump-seats so constructed and arranged. that one seat can be moved backward, under, and forward from under another,which is simultaneously moved backward and forward automatically-that is,

as one seat which is folded under another is moved forward and erected, the other is, by intermediate mechanism, moved backward, and vice versa.

rlhe invention consists in certain novel constructions andA combination of devices by which the relative movements of the seats are effected, and the two seats supported in their different positions, as will be hereinafter particularly described with reference to the accompanying drawings, in which-- Figure 1 is a vertical longitudinal section through the center of the body of a vehicle provided with jump-seats according to my intion, one seat being arranged for use and the other folded back under it. Fig. 2 is a similar view showing the seats both arranged for use, one being shifted backward and the other raised and jumped forward. Fig. 3 is a detached top view .of the locking-arms. Fig. et is atop view of the front seat with its sup,- porting-bars shown in dotted lines. a perspective view of one of the base or rocker plates, and a portion of the backseat and its connections.

The letter A indicates the body of the vehicle; B, the sills; C, the front seat, and J the back seat. R is a base or rocker plate shown secured to the inner 4side of the sill B; and it -will be understood that a similar plate is secured to the opposite sill, which plate, if desired, may be made in one or 4more pieces.

Fig. 5 isv From the upper edge of the rear portion of the base-plate R, a lug or standard, r2, is bent outward from the top of the baseplate across the top of the sill, and then projects upward from the outer edge of said sill. From the upper edge of the base-plate a lug, r3, is bent across the top of the sill and turned up slightly at its outer end.

The back seat, J,which may be constructed in any suitable manner, has secured thereto, under each end,a block, I, recessed,as shown, at its front end, and to the inner side of this block is secured a plate, l', the front portion of which is bent into the recess in the end of the block and then again forwardly, while its rear portion is connected to a leg, L, which is bent at Z to forma shoulder under the block.

To the rear end of the plate l is pivoted one end of a lever, N, which is pivoted at the top of the standard r', and has a short arm extending below its pivot. To the front end of the plate l is pivoted one end of a link, N the lower end of which is pivoted to the top of the standard r3, which projects from the outer edge of the sill. The front seat, C, is supported at each end on a horizontal bar-.- such as shown at K-and the ends of thisvbar are pivoted to the upper ends of arms F F, the lower ends of which are pivoted to the base-plate R on the inside of the sill, as will be seen clearly in the top View of the front seat in Fig. 4. The bar K, near its ends, has two inwardly projecting bends or lugs, k 7c, through which pass the bolts which hold the seat to the bar.

To the rear arm F on its inner side, is pivoted a bell-crank coupling-lever, S, with arms of different lengths, the short arm being turned downward, as shown in Figs. l and 2 in full lines. one end of a link, E', the other end of which is pivoted to an intermediate portion of a locking-lever, E, the front end of which is pivoted to the front arm F. The rear end of lthis locking-lever laps the link E', and has a laterally-projecting toe, e, which extends across the upper edge of said link. Said locking-lever has also an inwardly-projecting U -shaped bend, e', in which is arranged a pin, to which is pivoted one end of abrace-rod, E2, the other end of which is pivoted similarly to the op To this short arm is pivoted IOO posite locking-bar, as shown in dotted lines in Fig. 4. The long arm of the coupling-lever S is connected to the short arm of lever N under the back seat by a connecting-bar, D, the front portion of which is bowed upwardly to reach over the lever S, and is indented, as shown at d, so as to pass freely a pin, p,whieh projects inwardly from the rear arni F of the front seat. This pin p is intended to rest nearly upon the upperedge ofthe connectingbar D, so as to hold the connecting-bar D from raising and turning the link S and uneonpling it when the seat C is being pulled out from under seat J. So both seats take their position, as shown in Fig. 2, simultaneously, as is explained further on.

rlhe operation of the jump-seats as now dcseribed is as follows, it being of course understood that both sides of the body are equipped with similar seat operating and supporting mechanisms: Vhen the parts are in the positions shown in Fig. l, the seat .l only is arranged for immediate use, its leg L resting firmly upon the portion of the lug 7', which is bent across the top of the sill, while the long arm of the lever N serves as a brace to prevent the seat from swinging either forward or backward. It will be readily understood that this leg L need not be used when there is a frame at or near top of body for the seat to rest upon. The seat O may be folded back under seat J and out oi' the way, and its weight pressing against bar D,which is coupled to the short arm of leverN, holds the seat J` in place, as shown in Fig. l. 'When it is desired to use both seats, the seat C is grasped at any convenient point and pulled forward and upward until the arms F F stand vertically, or nearly so, as shown in Fig. 2. As these arms rise the connecting-bar D pulls forward the short arm of lever N, and consequently the seat .l is lifted and carriedrearward, descending again when t-he lever N passes the center or vertical position, so that the leg L rests upon the lug yr, which is bent across the top of the sill. The two lugs 1' and 1' thus serve as rests for the leg, in addition to the function of the lug 1' as a standard for pivotal connection with link N. As soon as the arms F F reach the upright position, the locking-lever E is to be pressed downward, so that its toe c rests upon the upper edge of link E, the locking-lever and link being thus brought in line and acting as a brace for the arms F F as the coupling-lever S is prevented from turning by the connecting-bar D. By following the connections from the foot ofthe leg L it willbe read ily seen that as long as the locking-bar E and link E remain in line both of the seats will be maintained in the positions shown in Fig. 2. Now, if it is desired to throw the seat C forward and lower it for a childs seat, or to allow the back seat to be easily reached, as shown in dotted lines in 2, the locking-lever E must be forced upward to break the lock, and

the arms F F being then swung forward and downward, the coupling-lever S will turn on its pivot, its long arm rising with the front end of the connecting-bar D, the bend d of which allows it to pass the pinp. The short arm of lever S rises at the same time, and the descending arms F F carry down the locking-lever E and link E until they again come in line with the toe c, :resting upon the upper edge of the link, thus forming a support upon which the rearward lug, k, of the bar l( rests, while the arms F F serve as braces.

If, instead ot' throwing the front seat forward from its upright position, it should be desired to fold it back and bring the back seat forward to the middle of the body, the first step would be the saine as before-thatis, theloek would be broken by forcing the locking-arm upward, and then forcing the front seat rearward until the pinp strikes the upper edge of the connecting-bar, the parts being thus in the positions shown in Fig. l.

Having new fully described my invention and explained the operation thereof, I claimn l.. The combination, with the base or rocker plate adapted for attachment to the sill, and provided with the leg-rests, of the swinging back seat having a leg, L, the front seat, and connecting mechanism, whereby when the front seat is shifted the back seat will. be also shifted, and its leg changed from one rest to the other, substantially as described.

2. The combination, with the front and back seats, of the lever N and link N', iivoted at their upper ends to the back seat and below to permanent supports, the arms F F, pivotally connected with the front seat at the top and to permanent supports at their lower ends, the coupling-lever S, pivoted to the rear arm F, the link FJ,v and locking-arm E, connecting the short arm of the couplinglever with front arm F, and the connecting-bar D, connecting the long arm ot' the coupling-lever with thc short arm of the operating-lever N of the back seat, substantially as described.

3. The combination, with the front and back seats, lever N, link N', and arms F F, of the coupling-lever S, link E, locking-lever E, provided with toe e, the pin p, projecting from rear arm F, and the connecting-bar D, bowed upward at its front portion and having the indentation s, all connected and arranged i'or operation substantially as described.

4. The front-seat supporting-bar K, having the bends 7c 7J, substantially as described, and for the purpose set forth.

In testimony whereof I affix mysi gnature in presence of two witnesses.
